Five sets of
thermoluminescence (TL) peaks with activation energy E = 0.50, 0.65,
0.75, 1.00 and 1.25 eV varying the frequency factor (s) over a zone 108
≤ s ≤ 1014 s-1 following the simple kinetics equation for order of kinetics b
= 1, 1.5 and 2 for various heating rates ( = 1, 2 and 5 °s-1), have been generated numerically. The results are compared with
experimental data in a general way in terms of peak temperature (Tm) as
well as the profile of the whole TL peak/TL curve that is relevant to
persistent luminescence. Computerized Glow Curve Deconvolution (CGCD) of some
of the experimental thermoluminescence (TL) data published in J Mater Chem, 15 (2005) 4025, has also been studied. Based on the simulated TL peaks
and analysis of the experimental TL curves, it is demonstrated that TL is
potentially a sensitive as well as useful technique in development and
characterization of materials exhibiting persistent luminescence. Finally, some
guidelines are provided to interpret the TL data without rigorous deconvolution
of the glow curves that has become the usual practice by practitioners of TL
researchers of the field of TL dosimetry.
